Appucation nlearugron 1o, 1923.v semaine. 624,125;

i The presentiiuvention relatesto spectacle temples, and it has for itschief object to pro-v vide a temple of the vnon-metallic type with` animproved,fiexiblehook.

With this and other objects in View, the nature of which will appearfrom the following description, taken `in connection `With theaccompanying drawings, the invention consists of the improvedarticlehereinafter described, illustrated 2in the accompanying drawings anddefined in the appended claims.

In the accompanying drawings, Figs. 1, 2 and 3 indicate three .stepsillustrative of the preferred method of makingthe temple of the presentinvention; Fig. 4 is av view of a preferred spectacle temple madeaccording to the preferred method; and Figs. 5 and 6 are sections takenupon the lines 5-5 and 6-6 of Fig. 4.

In manufacturing a temple embodying the present invention, it is Well tostart with a tube 2 of non-metallic material, like zylonite, celluloidand the like, tapering from the larger end or shank portion l towardsthe end 6 of smaller diameter. This material, though flexible, is Vnotsufficiently so in the form shown in Fig. 1 to produce, when the taperedend is` bent into the shape of a hook or loop, a temple that mayproperly be called flexible.. The portion of smaller diameter of thetube 2 is therefore cut intothe form of a spiral or helix, as shown at8, which renders it very yielding. By comparison, the uncut portions ofthe tube onboth sides of the cut portion are very rigid, so that asingle tubular member 2 is thus provided, having a. flexible loopportion 8 coextensive with a helically disposed cut extendingv throughthe walls thereof. A metal reinforcing rod or corelO is now inserted in'thev bore of the tube, and is fixed thereingin any well known manner,with the free end of the metal loop embedded inthe corresponding freeend of the' non-metallic material.` The said .end of the tube is closedby a plug, as

illustrated. V.The rod l() may be of the same` material of whichflexible metal temples are then bent intoa hook or .templeshapd leavving the. shank portions ofthe tube ,and the metal rod lOrelativelystraight, -asfshownin Fig. 4,1fand the customary hinge plate l1.2is'added, completing the temple.` i i n rQ lhe temple of the presentinvention may,

ofcourse, be manufactured .also inl other Waysthanthat described above,the :present application covering the article'and not gitiS, l

method of manufacture.

Modifications. will occur ,to persons skilled in theartxwithin thespirit and-,scope ofthe appended claims. y .'Whatis claimed is: l Y Il.vAs an article of manufacture, atube constituted of non-metallicmaterial into which a flexible rod is inserted,.a portion of the` tubebeing cut into the form of a spiral, Y

and the cut portion ofthe tube and the rod inserted therein being bent.Y

2.V A spectacle temple comprising a tapered Ytube constituted offlexible, non-metallic material into which is inserted a vmetalreinforcing ,rod, a portion Aof smaller' diameter of the tapered tubebeing cut into theV form of a spiral, and the cut portion of the tubeand the reinforcing rod'V insertedvtherein being 'bent into' the shapeof a temple.

3. Aspectacle temple co-mprisinga metal `core having a relativelystraight shank portion anda loop portion, and a non-metallic coveringfor the core comprising a single tubular member, the portion of thetubular l member that covers the loop portion of the core being cut intothe form of a helix, and the corebeing fixed in the covering.

4. A temple for vspectacles and the like comprising a met-al core havinga relatively straight shank portion and a loop portion, and anon-metallic covering for said core consisting of a .single tubularmember hav-V ing a liexible loop covering portion coexF tensive with a.helically disposed cut extending through the Awall thereof, oneend of`said covering having the free end of the loop Y Y embedded' therein.

5. A temple for spectacles and the like comprising a met-al corehaving'a relatively'v through the wall thereof, one end of said coveringbeing closed and having the free end of the loop embedded therein.

6. A temple for Spectacles and the like comprisinga metal core having arelatively Straight shank and a loop, and a nonmetallic covering forsaid core consisting of a tubular member having a flexible portioninterposed between relatively rigid portions and co-extensive With ahelically disposed eut extending through the Wall of said tubularmember, and one of said rigid portions being positioned on the core toengage the free end of the loop.

7. A spectacle temple comprising a reinforcing core having a relativelystraight Shank portion and a rear portion, and a nonl metallic coveringfor the core covering the shank portion and the rear portion, theportion of the covering that covers the rear portion of the corecomprising a tubular member that is cut into the Jform of a helix, andthe core being fixed in the covering.

8. A spectacle temple comprising a metal core having a relativelystraight shank portion and a flexible loop portion, and a nonmetalliccovering ior the core covering the shank `portion and the loop portion,the covering comprising a single tubular meu1- ber, the portion of thetubular member that covers the loop portion of the core being cut intothe form of a helix, whereby the helically cut portion ofthe tube isstiifened by the loop portion of the core but has substantially the samedegree of flexibility as the said loop portion of the core.

9. A spectacle temple comprising a metal core having a relativelystraight shank portion and a flexible rear portion, and a nonmetalliccovering for thecore covering the shank portion and the rear portion,the por tion ot' the covering that covers the rear portion of the corecomprising a tubular member that is cut into the form of a helix,whereby the helically cut portion of the tube is stiened by the rearportion ol the core hut has substantially the same degree offlexibility' as the said rear portion of the core.

In testimony whereof, I have hereunto subscribed my name this 7 th dayof March,

JAMES lV. WELSH.
